Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat transfer member such as a heat transfer tube or a heat transfer plate for heat exchange used in various industrial fields, and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, for heat exchangers and heat exchange materials for liquid-liquid, liquid-gas, gas-gas, etc., metal heat transfer tubes and heat transfer tubes made of copper or aluminum, which generally have high thermal conductivity, are used. Boards are used. However, the exchange heat capacity is said to be determined by the temperature difference between each heat medium, the heat transfer characteristics, the heat transfer area, etc.
Especially when downsizing of the heat exchanger is required, not only materials with high thermal conductivity are used, but also fins and grooves are provided on the surfaces of the heat transfer tubes and heat transfer plates to increase the heat transfer area. By devising the structure, turbulent flow is generated in the heat medium to increase the heat transfer characteristics. Further, in Japanese Patent No. 1435526 and Japanese Patent Application Laid-Open No. 4-110597, a heat transfer area and a heat transfer characteristic are simultaneously increased by depositing a porous body or a foamed body of copper or a copper alloy on a heat exchanger. There are also proposals for miniaturization.

[0003]

However, Japanese Patent No. 143
No. 5526 and Japanese Patent Laid-Open No. 4-110597, when a porous body or a foam of copper or a copper alloy is applied, the former and the former are designed to bond or adhere to a heat transfer member. After injecting and solidifying, the method of melting the foam shape mold is adopted.In the latter case, further means such as crimping, brazing, plating, etc. in the final step for firm joining of the porous body and the heat transfer member. There is a problem in that the manufacturing cost is increased due to increase in equipment cost and manufacturing cost beyond the effect of simply increasing the required heat transfer area. Further, in the production of the heat transfer tubes in these proposals, there is also a drawback that they cannot be simultaneously adhered to the inside and outside of the tube. The present invention is intended to solve such a problem, and has a three-dimensional mesh having a large surface area per unit volume and a large porosity on a heat transfer member body such as a metal plate or a metal tube having good heat conduction. The present invention provides a heat transfer member having a strip-shaped structure and a batch manufacturing method thereof.

[0004]

According to the present invention, metal powders such as gold, silver, copper, nickel, aluminum, titanium, chromium, zinc, tin, manganese, tungsten and cobalt are heated in an inert or reducing atmosphere. Each of them utilizes the property of being easily sintered alone or as a mixture, and is for producing a metal-sintered body joined to the surface of a metal member or a metal-member joined body having a structure sandwiching a sintered body. . That is, a metal sintered body is formed into a three-dimensional mesh structure and is integrally sintered on the surfaces of metal plates of the same material, between metal plates, and inside and outside of a metal pipe, so that a heat transfer plate or heat transfer tube with high heat transfer efficiency is obtained. Is what you get.

FIG. 1 is a process chart showing an example of a process up to before sintering in the manufacturing method of the present invention. First, as a method for obtaining a metal three-dimensional network structure having a large surface area per unit volume and a large porosity, (1) a three-dimensional network structure made of a material which is burned down by heating, such as urethane foam,
Adhesive is applied to the skeleton of synthetic resin foam with open cells such as polyethylene foam, natural fiber cloth, artificial fiber cloth, etc., and single metal powder, multiple mixed metal powder or fine metal fibers in the gas phase, etc. A method of using a molded body to which a metal powder material is applied, (2) a material made of a material that is burned down by heating and capable of forming a three-dimensional network structure, such as pulp or wool fiber (3) Slurry in which metal powder such as metal powder or fine metal fiber is previously kneaded with synthetic resin itself such as urethane foam or polyethylene foam before foaming -Method using a resin, (4) Conductive treatment is applied to the skeleton of the three-dimensional network structure such as urethane foam, polyethylene foam, natural fiber cloth, artificial fiber cloth, etc. Electric It is possible to use a method of using a molded body on which a metal film is deposited by a vapor plating method or an electroless plating method.

[0006] Next, in the case of (3), the slurry-like resin is applied to the intended portion in advance, or if it is a metal pipe, it is filled and then foamed. Although it may be sintered by sintering, in the other three methods, in the case of a metal plate, the metal three-dimensional network structure is pressure-bonded to one side or both sides. Moreover, it is sandwiched between two metal plates and pressure-bonded. At this time, in order to enable stronger bonding between the metal three-dimensional mesh structure and the heat transfer member main body, an adhesive is applied to the surface of the metal plate, and then metal powder of the same material is applied. It is desirable to put the adhesive or to apply the adhesive mixed with the metal powder. That is, it is intended to strengthen the sintering between the member and the three-dimensional network structure by increasing the contact between the metal powders, and the mutual anchor effect is increased and the surface area is further increased.

Similarly, in the case of a metal tube, a target surface is coated with a pressure sensitive adhesive or metal powder is applied in advance to crimp the metal three-dimensional mesh structure. At this time, the outer surface of the metal pipe can be easily coated by winding it in a spiral, but the inner surface of the pipe is coated in advance with a cylindrical mesh-like structure having an outer diameter slightly larger than the inner diameter of the metal pipe and fitted. If it is inserted, insert it. Also,
The metal three-dimensional mesh structure can be formed by stacking a plurality of structures having different mesh diameters, that is, pore diameters in advance, and pressure bonding or stacking for several orders. Further, in the case of the above (3), it goes without saying that the same laminated pressure bonding to the heat transfer material portion coated with the slurry-like resin is also possible. In addition, a plurality of metal pipes may be simultaneously wrapped with a metal three-dimensional network structure, or the metal three-dimensional network structure may not be formed into a block shape and penetrate a plurality of metal pipes to form a three-dimensional structure. It can also be the material of the heat transfer member.

Next, the method of sintering the metal member on which the three-dimensional network structure is laminated, bonded or applied is as follows: removal of the base material of the three-dimensional network structure, sintering of metal powders, and further metal member. It is necessary to integrate sintering with. First, as a method of removing the base material and the adhesive material, any of the animal, vegetable fiber, and synthetic resin can be burnt and removed by heating and roasting in an inert or reducing atmosphere, or heating and burning in a gasification or oxidizing atmosphere. At this time, if the metal powder is a metal oxide, in an inert or reducing atmosphere, oxygen in the metal oxide is consumed by heating and roasting the carbon and hydrogen sources in the base material while the metal powder is pure. Sinter as metal. In an inert atmosphere, a gas such as nitrogen, argon, or helium is used. In a reducing atmosphere, hydrogen gas, hydrocarbon gas, water gas, ammonia gas, or the like is introduced, and a hydrocarbon compound or a sulfur compound is further added to the base material. By premixing and kneading the phosphorus compound and the hydride, it is possible to achieve more aggressive sintering in a reducing atmosphere. However, if the base material of the three-dimensional network structure used is an inert atmosphere, is difficult to gasify in a reducing atmosphere and is easily carbonized, air is introduced to burn and burn in an oxidizing atmosphere, and then the aforementioned hydrogen gas, hydrocarbon A two-stage sintering method is performed in a reducing atmosphere such as gas, water gas, or ammonia gas. At this time, the reducing atmosphere is not limited to the gas phase, but may be in the liquid phase. That is, it can be achieved by adjusting reducing conditions such as liquid temperature and pH in an aqueous solution of alcohols, aldehydes, sugars, hydrides and the like.

By the above method, a heat transfer member can be obtained by sintering the metal three-dimensional mesh structure on the surface of the heat transfer member main body made of a conductive metal such as a metal plate or a metal tube. As a method for increasing the specific surface area of the heat transfer member, fine irregularities can be applied to the skeleton of the mesh structure by electroplating or electroless plating. In electroplating, the heat transfer member is
-Dentrite-like metal is deposited by plating the same metal material or a different metal material that can be plated at a relatively high current density in an electroplating bath. In electroless plating, a metal deposition similar to electroplating can be obtained by making the loading factor (plating area / plating bath volume) relatively high.

Further, considering the use as an actual heat transfer material, it is also possible to impart preliminary oxidization and wettability of the heat transfer surface which also has corrosion resistance and, in some cases, water repellency to the performance and characteristics. It is an effective way to improve. In the former, as mentioned above, heating oxidation in the gas phase or ozone oxidation and peroxide aqueous solution,
This can be done by liquid-phase oxidation of an alkaline aqueous solution or the like. In the latter case, it can be done by applying a silicate hydrophilic paint or Teflon paint.

【Example】

Example 1 A three-dimensional mesh structure having a thickness of 3, a width of 5 and a length of 20 mm.
Nine polyurethane foams (trade name: Everlight SF, made by Bridgestone, average pore size 0.6 mm), length 60
3 mm were used. An adhesive was applied to these polyurethane foams to give tackiness, and then dried. Next, insert each of these into copper oxide powder, copper powder, and three types of mixed powder of copper powder and nickel powder, shake them to sufficiently deposit metal powder in the gas phase, and then in water. The metal powder that had been excessively adhered was peeled off by immersing in water and rocking, and at the same time, the skeleton of the polyurethane foam was uniformly adhered. On the other hand, six copper plates having a similar area and a thickness of 0.6 mm were prepared as metal members, and metal powders corresponding to the respective copper plates were sufficiently uniformly adhered to the copper plate surface together with an adhesive. Also, three copper pipes having a diameter of about 20 mm were prepared as metal pipes, and metal powders corresponding to the respective copper pipes were similarly adhered to the outer surfaces thereof together with an adhesive. Next, three types of polyurethane foam coated with metal powder, a copper plate and a copper tube were laminated and joined. First of all, the heat transfer plate is a polyurethane foam made by coating a copper plate with three types of metal powder.
One side and both sides were lightly laminated by a roll press. Similarly, a heat transfer tube was prepared by pressing and winding a polyurethane foam coated with three kinds of metal powder. Then, when these 9 kinds of heat transfer members were heated at about 500 ° C in an electric furnace while supplying air, the adhesive and the polyurethane foam which was the base material were burned down, but the metal powder became a copper plate in a three-dimensional mesh. It remained as a sintered body having the skeleton of the structure. Next, these were further heated in an electric furnace at about 900 ° C. while introducing a mixed gas of hydrogen and nitrogen to carry out reduction sintering. As a result, as shown in FIGS. 6, 7 and 8, heat transfer members of three metal types and three shapes could be obtained.
At this time, the porosity of the metal three-dimensional network structure on the member was 96% in all, but the heat transfer plate using copper oxide as the raw material metal powder and the metal copper three-dimensional network structure on the heat transfer tube. In the reduction sintering, the volumetric shrinkage ratio was about 50%, and there was a portion that was not adhered to the periphery of the heat transfer plate and the end of the heat transfer tube. Then, by rolling this heat transfer plate in the width direction and brazing the end portions in the length direction, a metallic copper three-dimensional mesh structure was obtained inside and outside the pipe.

Example 2 A three-dimensional mesh structure having a thickness of 3, a width of 5 and a length of 60 mm.
Polyurethane foam (trade name: Everlite SF, made by Bridgestone) A, B two types (A: average pore size 0.6 mm)
And B: average pore diameter 0.8 mm), and two sheets were used. An adhesive was applied to these polyurethane foams to give tackiness, and then dried. Next, these are inserted into the copper oxide powder flowing in the air in a pair of A and B, and the copper oxide powder is adhered, then immersed in water and rocked to remove the excessively adhered copper oxide powder. At the same time, the skeleton of the polyurethane foam was uniformly applied. Next, two copper tubes having an inner diameter of about 13 mm and an outer diameter of about 16 mm were prepared in the same manner as in Example 1. One of the tubes was wound with B first on the surface and then A on the spiral. It was At the same time, the other tube was fitted and inserted into a tube in which A and B were preliminarily overlapped with each other while forming a cylinder so that B was on the tube wall side. Next, one of the former was subjected to reduction sintering at 900 ° C. by directly introducing a mixed gas of nitrogen gas and hydrogen gas in an electric furnace. Polyurethane foam
-The gas was vaporized and volatilized, but the copper oxide powder was reduced to metallic copper to form a two-layer metallic copper three-dimensional network structure with different pore diameters, and the outer surface of the tube covered by shrinkage. I was able to get At this time, as the reducing gas, in addition to hydrogen, hydrocarbon gas, hydrogen sulfide gas, ammonia gas, water gas and the like can be used. On the other hand, for the one inserted in the other tube, first introduce air in an electric furnace to burn and burn the polyurethane foam, and then add formaldehyde solution with reducing action in alkaline solution while heating. As in the former case, a heat transfer tube having two layers of metal-copper three-dimensional network structures (A, B) having different pore diameters could be obtained as in the former case (FIGS. 9 and 10). As the reducing solution, sodium borohydride, sodium hydrogen carbonate, soda sulfide, alcohol and the like can also be used. However, compared with the gas reduction method, the solution reduction method requires a long time to reduce the entire skeleton of the three-dimensional network structure, and the strength is low, but the metal powder should be made as fine as possible. It can be applied depending on the purpose of the heat transfer tube.

Example 3 A three-dimensional mesh structure having a thickness of 3, a width of 5 and a length of 60 mm.
Polyurethane foam (trade name: Everlite SF, made by Bridgestone Co., average pore size 0.6 mm) is used, thoroughly washed in an alkaline solution, further thoroughly washed with water, and then activated with palladium chloride, etc. After the treatment, a form was obtained in which the surface of the skeleton of the three-dimensional network structure was copper-plated in an electroless copper plating bath. This is laminated on the surface of a copper plate or copper tube to which copper powder is adhered in the same manner as in the above-mentioned example, and burned and burned with air and reduced and sintered with hydrogen gas in an electric furnace to obtain a heat transfer plate or tube. (Figs. 11 and 12).
Further, these heat transfer members obtained here are subjected to electroplating under high current density as a cathode in a copper sulfate plating bath to have a dentrite-like shape over the entire surface of the heat transfer member, which has a larger surface area and strength. It was possible to obtain a large heat transfer member. At this time, the electroplating may be the electroless copper plating in the previous stage, or electroless nickel plating or noble metal plating such as gold or silver plating, if necessary.

Example 4 A sheet was prepared by dispersing fine copper oxide powder, pulp fibers and an adhesive in a solution, papermaking and drying. At this time, the weight ratio of copper oxide to pulp is preferably 30% or more. It was possible to obtain a heat transfer plate or a heat transfer tube by laminating this dry sheet on a copper plate or a copper tube as in the above-mentioned embodiment, and further burning and burning with air and reduction sintering with hydrogen gas in an electric furnace. (Fig. 1
3, 14). At this time, in parallel, monofilament wool, methylcellulose
It was possible to obtain a three-dimensional network structure with different porosity on the heat transfer member even with carbon, activated carbon fiber, granular activated carbon, etc.

Example 5 A urethane paint prepared by mixing fine copper oxide powder with a urethane resin mixed with a foaming agent in advance and imparting fluidity with a solvent,
The copper plate was coated on the surface, and the copper tube was press-fitted inside and coated on the outside, then heated and foamed. As described above, these were burnt and burned with air in an electric furnace and reduced and sintered with hydrogen gas, and a heat transfer plate with a copper three-dimensional mesh structure on the front and back and a copper three-dimensional mesh over the entire tube volume inside It was possible to obtain a heat transfer tube having a three-dimensional mesh structure on the outside with the linear structure inserted therein (FIGS. 15 and 16). The porosity of the copper three-dimensional network structure inside the tube can be adjusted by changing the foaming conditions such as the foaming agent and the temperature. At this time, more sulfur in the paint,
A heat transfer member could be obtained by only mixing phosphorus, soda sulfide, sodium hydrogen carbonate, sodium borohydride, etc. in the anoxic state.

Example 6 The heat transfer members obtained in Examples 1 to 5 may be easily oxidized depending on the use conditions. As a countermeasure against this,
There is a method of pre-oxidizing. That is, it is easily oxidized in a solution of peroxoammonium, potassium permanganate, soda perchlorate or the like. In addition, it was possible to improve or maintain electric heating performance by improving wettability by coating a hydrophilic coating material containing silicon dioxide in order to cope with corrosion.
